It says there is no flight school but it does say there are two single engine planes based on the airport there. How old this info is I don't know but if there are planes there there is always the possibility of asking one of the owners if you can go up with them (I'm guessing you won't be able to rent off a private owner because of insurance).

It lists 5 aircraft on the island and has the owners names and addresses but unfortunately not email or telephone numbers. I'm not sure how up to date the info is or if you can find there emails online or something.
